Is there a dark side to the moon? Earth exerts tidal forces on the moon’s rocky interior -> It is rotating with the same period around its axis as it is orbiting Earth (tidally locked) -> We always see the same side of the moon facing Earth

12.
The Moon is seen to keep one face toward Earth at all times. If viewed from a point directly above the plane of the planetary system, how does it have to rotate to maintain this alignment? Q?

It must rotate once per year as Earth and Moon orbit the Sun together.

It must rotate once per day.

It must not rotate at all, since we always see the same face from Earth.
